| Abstract: | On the base of data investigation with point-centred quarter method, the community structure composition of Tamarix elongata distributed on sale dune in middle reaches of Shule River was described. The association relationship of spatial pattern and interspecific ecological distribution of the dominant species in community was studied by using the methods of theoretical fitting by discreted distribution model, aggregate intensity indexes and interspecific association detection. |
